DETAILED DESCRIPTION OF THE INVENTION
[0030] As shown in FIGS. 1-5, a sport sandal 1 embodied in the
present invention comprises the component parts, which are
described hereinafter.
[0031] A sole 10 of a predetermined thickness is formed of a block
body 11 having a side surface 12, a first through hole 13, and a
second through hole 14. The two through holes 13 and 14 have a long
cross section, an opening 131, 141, a top 15. The openings 13 and
14 are provided with a U-shaped protection wall 16. The top 15 is
provided with a strap placing recess 17 in communication with the
through holes 13 and 14. The recess 17 is provided at the top of
the outer side thereof with a stop lug 18.
[0032] A midsole 20 is adhered to the top 15 of the sole 10.
[0033] A first strap 30 is of a shoe-shaped body 31 and is provided
with a placing tape 32 which is in turn provided at the front end
with a guide piece 33 which is provided with a hook hole 331. The
placing tape 32 can be put through the opening 131 of the first
through hole 13 of the sole 10 by means of a tool "A", and two ends
thereof with a joining portion 35, 36.
[0034] A second strap 50 is of a shoe-shaped body 51 and has a
placing tape 52 which is provided at the front end with a guide
piece 53 having a hook hole 531. The placing tape 52 is put through
the opening 141 of the second through hole 14 of the sole 10 by
means of the tool "A". The second strap 50 is provided at two ends
with a joining portion 55, 56.
[0035] The placing tapes 32 and 52 of first strap 30 and the second
strap 50 have a cross section of a long strip shape. The joining
portions 35 and 55 are male retaining tapes 71. The joining
portions 36 and 56 are female retaining tapes 72 capable of joining
with the male retaining tapes 71.
[0036] The midsole 20 is provided thereon with a sole touching body
80 made of an elastic fiber filament block and intended to be
treaded on by the foot sole, or a shoe pad of other forms.
[0037] As shown in FIG. 6, the assembly of the present invention is
attained by a tool "A" having a cord body A1, which is provided at
one end with a fitting ring A3. The cord body A1 is provided at
other end with a hook ring A5. As shown in FIG. 7, a pull handle C
has a T-shaped grip C1 and a hooked portion C3 for hooking and
pulling the hook ring A5 of the tool A.
[0038] As shown in FIG. 8, the tool A is put through the through
holes 13 and 14 such that the fitting rings A3 catch the hook holes
331 and 531 of the straps, and that the hooked portion C3 of the
pull grip C hooks to pull the hook ring A5 of the tool A. The
placing tapes 32 and 52 of straps 30 and 40 are thus put through
the through holes 13 and 14 of the sole 10.
[0039] The bodies of the straps 30 and 40 are retained in the inner
side of each stop lug 18 of the sole 10 to prevent the escape of
the straps from the recess 17. Finally, the male and the female
retaining tapes 71 and 72 of the joining portions 35, 36, 55, 56 of
the straps 30 and 40 are joined together.
[0040] The protection wall 16 serves to prevent the friction of the
straps 30 and 50 by the foreign objects. The stop lug 18 serves to
prevent the displacing or the loosening of the strap.
[0041] The joining portions of the present invention are not
confined to the male retaining tape 71 and the female retaining
tape 72 and may be replaced with a male retaining button and a
female retaining button, or a plurality of insertion holes disposed
in the joining portion of the straps and a retaining rod disposed
at other joining portion. The retaining rod is inserted into the
insertion holes.
[0042] As shown in FIGS. 9-11, the strap of another preferred
embodiment of the present invention is provided with a tape
retainer 60 of a triangular frame strip, and two placing tapes
which are put through the two through holes. The placing tapes are
provided at the front end with a horizontal tape hole 38, 58. The
tape retainer 60 is provided with a cut 63 and a threaded rod 65
which is engaged with a nut 67.
[0043] As shown in FIG. 10, a pull cord E has a cord body E1 which
is provided at both ends with a hook ring E5, and a tape hook G
capable of being hooked and pulled by the hook ring E5 of the pull
cord E. In combination, as shown in FIG. 11, the tape holes 38 and
58 are caught by the tape hook G. Thereafter, the strap is pulled
by the pull cord E and the pull handle C such that the hole 58 is
joined via the cut 63 of the tape retainer 60.
[0044] As shown in FIG. 12, this preferred embodiment is provided
with only one strap which is provided with two placing tapes for
putting through the two through holes.
[0045] The sole of the present invention is not confined to have
two through holes or two straps. As shown in FIG. 13, the sole of
the present invention is provided with two straps 30B and 50B, with
the strap 30B being provided with two placing tapes 32B. As shown
in FIG. 14, the sole has a third through hole 15A for receiving one
placing tape 32B. The present invention may be provided with a
plurality of through holes and straps of various forms.
[0046] In addition, the sole is provided with more than two through
holes, which are not necessarily parallel to one another, or
intersected. As shown in FIG. 15, the sole of the present invention
is provided with the through holes 13B and 15B, which are
intersected to facilitate the assembly of straps of various
forms.
[0047] As shown in FIG. 16, the sole of the present invention has
areas which are devoid of the through holes and are provided with a
plurality of ribs 19A and recesses 19B for reinforcing structural
strength of the sole and for reducing the weight of the sole.
[0048] The through holes of the sole are not necessarily located in
two sides of the sole. As shown in FIG. 17, the openings 131A and
141A of the through holes of the sole are located at the left top
and the right top of the sole.
[0049] As shown in FIG. 18, the protection walls 16A may be
disposed in two sides of the outside of the openings. As shown in
FIG. 19, a protection wall 16B is disposed in the lower edge of the
opening of the through hole to provide the strap with protection
against friction.
[0050] As shown in FIG. 20, the joining of the strap of the present
invention may be attained by a triangular tape retainer 60A which
is provided in two sides with a tape body. The tape retainer 60A
has an insertion rod 61A which is provided with a threaded member
63A, a threaded rod 65A and a notch 67A. The placing tape has a
tape hole 58 and is joined with the insertion rod 61A via the notch
67A. As shown in FIG. 21, the tape retainer 60B may be of a
tetragonal construction.
[0051] As shown in FIG. 22, the placing tape of the strap is
detachably joined with an insertion retainer 60C which has two lugs
61C and 62C, which are in turn provided with a through hole 63C and
a threaded hole 64C. An insertion rod 67C is received in the
through hole 63C. The insertion retainer is not confined to the
male insertion retainer or female insertion retainer.
[0052] The present invention has advantages. In the first place,
the sole and the straps of the present invention are
interchangeable. As a result, the versatile sandals are made to
provide the consumer with a wide range of selection. The sole and
the straps of the present invention are made of different materials
and can be easily recycled. The present invention is versatile in
design and cost-effective.
